Method Detail

registerReifier

public static void registerReifier(Class<?> errorHandlerClass,
                                   BiFunction<org.apache.camel.Route,org.apache.camel.ErrorHandlerFactory,ErrorHandlerReifier<? extends org.apache.camel.ErrorHandlerFactory>> creator)

reifier

public static ErrorHandlerReifier<? extends org.apache.camel.ErrorHandlerFactory> reifier(org.apache.camel.Route route,
                                                                                          org.apache.camel.ErrorHandlerFactory definition)

createExceptionPolicy

public org.apache.camel.processor.errorhandler.ExceptionPolicy createExceptionPolicy(OnExceptionDefinition def)

lookupErrorHandlerFactory

public static org.apache.camel.ErrorHandlerFactory lookupErrorHandlerFactory(org.apache.camel.Route route,
                                                                             String ref)

Lookup the error handler by the given ref

Parameters:

route - the route context

ref - reference id for the error handler

Returns:

the error handler

lookupErrorHandlerFactory

public static org.apache.camel.ErrorHandlerFactory lookupErrorHandlerFactory(org.apache.camel.Route route,
                                                                             String ref,
                                                                             boolean mandatory)

Lookup the error handler by the given ref

Parameters:

route - the route

ref - reference id for the error handler

mandatory - whether the error handler must exists, if not a NoSuchBeanException is thrown

Returns:

the error handler

lookupErrorHandlerFactory

protected static org.apache.camel.ErrorHandlerFactory lookupErrorHandlerFactory(org.apache.camel.CamelContext camelContext)

isErrorHandlerFactoryConfigured

public static boolean isErrorHandlerFactoryConfigured(String ref)

Returns whether a specific error handler builder has been configured or not.

Can be used to test if none has been configured and then install a custom error handler builder replacing the default error handler (that would have been used as fallback otherwise).
This is for instance used by the transacted policy to setup a TransactedErrorHandlerBuilder in camel-spring.

addExceptionPolicy

public void addExceptionPolicy(org.apache.camel.processor.errorhandler.ErrorHandlerSupport handlerSupport,
                               OnExceptionDefinition exceptionType)

createExceptionClasses

protected List<Class<? extends Throwable>> createExceptionClasses(OnExceptionDefinition exceptionType)

createErrorHandler

public abstract org.apache.camel.Processor createErrorHandler(org.apache.camel.Processor processor)
                                                       throws Exception

Creates the error handler

Parameters:

processor - the outer processor

Returns:

the error handler

Throws:

Exception - is thrown if the error handler could not be created

configure

public void configure(org.apache.camel.processor.ErrorHandler handler)

createRedeliveryPolicy

public static org.apache.camel.processor.errorhandler.RedeliveryPolicy createRedeliveryPolicy(RedeliveryPolicyDefinition definition,
                                                                                              org.apache.camel.CamelContext context,
                                                                                              org.apache.camel.processor.errorhandler.RedeliveryPolicy parentPolicy)

Note: Not for end users - this method is used internally by camel-blueprint

getPredicate

protected org.apache.camel.Predicate getPredicate(org.apache.camel.Predicate pred,
                                                  String ref)

getBean

protected <T> T getBean(Class<T> clazz,
                        T bean,
                        String ref)
